Roller Coaster Tycoon, Zoo tycoon is like wow look how many people i got into my Zoo to look at animals. With Roller Coaster Tycoon you can build, design, and ride yor roller coasters. There is so much more you can do with rollercoatser tycoon

if you like animals and the zoo try Zoo Tyconn, caution at the fence type. :D
If you like to have fun with roller coasters, try Roller coaster tycoon. Do not sent the people in mid air with the roller coaster (it's fun but expensive)
